The Charger isn't a great example of using the touch screen for "most controls", because if the inside of your Charger looks anything like this (I just Googled for a photo)
Then you have buttons and knobs for turning the sound system on and off, adjusting the volume, adjusting the temperature, turning the fan on and off, adjusting the fan speed, toggling the A/C, recirculating air, front defrost, and rear defrost, as well as having a physical knob to scroll through and select options on the screen.
I'm sure that there are additional things you can do on the screen, like navigation and more advanced climate control, but you can definitely operate the important controls without needing to take your eyes off the road. That's the complaint about the Tesla screen - not that it exists, but that there aren't buttons and knobs for the important controls.
